I wrote a WordPress plugin recently called Admin Stylur and I thought this would be a good time as any to explain the process a bit and share some inside knowledge I gained while submitting to the WordPress plugin directory. This won’t be one of those posts where I tell you each facet about making a plugin or how to generate that awesome plugin idea. I’m simply saying “here are a few things I caught along the way and here is a post about said things.” Hopefully all that will help to make the process more simplistic, and less stressful as you begin.

To start, plugins submitted to the WordPress plugin directory are required to use SVN. To those not familiar with SVN, it’s a bit like Git only weirder. I won’t take the time to explain SVN, but here are some links to get you started.
In order to be accepted into the plugin directory you have to have a solid and validated README.txt
which you can validate using this simple validator tool from WordPress. Here’s a few tips you may want to know about before you validate your README
and make your first SVN commit:
The Tips
- Make sure your main heading sections in your
README.txt
look like this - Make sure your screenshots are labeled
screenshot-[1|2|3|..].png
and tucked into your SVNs“assets”
directory. When your screenshots have been properly ordered and named it will look like this in yourREADME.txt
when you’re done. - Banner images used for the plugin directory has to be named “
banner-772x250.png
” and placed in your project’s SVN “assets
” directory. For retina you can use “banner-1544x500.jpg
.” Full details are listed here. No GIFs. - Screenshots in the “
assets
” directory take precedence over screenshots in the plugin’s directory. README.txt
files can accept Markdown formatting. Don’t be scared.- Do your best to make sure the plugin directories banner caption is no more than 22 words or 150 characters. This piece of text is pulled from your plugins
README.txt
file and looks like this - The plugin page in the directory should include no more than 12 tags
- Last, but not least have fun!
If you need a helpful template for your plugins banner and icons take a look here for a full blown PSD that contains a preview of what the plugin’s banner will look like once it’s published to the plugin directory, a retina template along with icon templates for the plugin directory. When using these templates make sure you have Helvetica Neue installed for best representation of the real thing.
I hope these tips help to make the process a bit more friendly and give you the proper warnings and heads up needed to make your plugin look super awesome for the WordPress plugin directory. If you have any questions feel free to leave a comment or give me a shout on Twitter.
Thanks Dennis for the tips. Do you also happen to know how to upload an image for my plugin for the plugin overview? http://screencast.com/t/11QrRSMpn. I’ve been looking for a while now and cannot find an answer.
NP Steve. As you can see in this screenshot the naming convention must be in a particular fashion http://cl.ly/image/2U3R1g3E0l1r.
If you’re only using raster (i.e. .png) it would look like this…
or if you have a vector it would be…
I also presented on this at WordCamp Buffalo which you can see those slides here http://speaking.grayghostvisuals.com/wordcamp/2014/designing-for-wordpress/#/8/2
TIP: You can also open up DevTools and inspect the markup on that view if you wanna know the size of the icon in case you forget ;)
